Zimbabwe topping this list can hardly be surprising given all of the turmoil that the country is currently going through. Zimbabwe is basically ostracized from the rest of the world right now, and they are fighting through a number of unique challenges, including political turmoil and rampant hyperinflation.

It's no wonder that 9 out of every 10 working adults can't find a job in that country.

Zimbabwe has some company at the top of the list - Nauru also possesses an unemployment rate of 90%, according to the CIA Fact Book.
